SORRY but even for the smallest of terrapins you will need a bigger tank, you need to fit in a filter, a water heater (not a fish water heater they can be bitten through) a land area and a water area, a basking light, (this is the minimum requirements) so the dimensions you give will be too small for a terrapin, why not sell it and put the money towards getting a bigger tank, you have picked nice names though, best of luck.2 years ago
